Reports Outline Membrane Science Study Results from KAUST

February 25, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Membrane Science. According to news originating from Thuwal, Saudi Arabia, by VerticalNews correspondents, research stated, "A simple and efficient approach towards the fabrication of a skinned membrane with highly ordered pores in the nanometer range is presented here. We successfully combined the self-assembly of PS-b-FED block copolymer and water induced phase separation for the preparation of isoporous PS-b-FED block copolymer membranes."

Our news journalists obtained a quote from the research from KAUST, "We produced for the first time asymmetric isoporous PS-b-FED membranes with a 100 nm thin isoporous separating layer using water at morn temperature as coagulant. This was possible by careful selection of the block lengths and the solvent system. FESEM, AFM and TEM measurements were employed to characterize the nanopores of membranes. The pure water fluxes were measured and the flux of membrane was exceptionally high (around 800 Lm(-2) h(-1) bar(-1))."

According to the news editors, the research concluded: "Protein rejection measurements were carried out for this membrane and the membrane had a retention of about 67% of BSA and 99% of gamma-globulin."
